Can I Wind Turbine Power a House?

The answer, of course, is yes, a wind turbine can power a house.

The specific need to buy more power wind turbine, it needs to see how many household appliances your house needs to load, the following is the power of the household wind turbine and their matching household load, you can choose according to your actual situation.

Mini generators in general are: 300 w, 500 w, 1000 w, 3 kw, 5 kw, 10 kw, 20 kw several.

300W wind turbine, small power, can only be used for TV, lighting, electric fans.

500W fan can carry TV, lighting, electric fan, washing machine slightly more than 300W.

1-2KW fan can be used for TV, lighting, electric fan, washing machine, small refrigerator.

3KW wind turbine is more, can be used for TV, lighting, electric fan, washing machine, refrigerator, rice cooker, water pump, air conditioning power.

The 5KW wind turbine can be equipped with TV, lighting, electric fan, washing machine, refrigerator, rice cooker, water pump, air conditioning and other appliances.

10KW fan can be used for TV, lighting, electric fan, washing machine, refrigerator, rice cooker, water pump, air conditioning, and small village lighting.

20KW fan can be used for TV, lighting, electric fan, washing machine, refrigerator, rice cooker, water pump, air conditioning and other electrical appliances, small village lighting and so on.

But the best solution is a wind-PV system, which can generate electricity for a long time and store it in a battery for home use. When there is sunshine during the day, the solar energy is converted into electricity, which will also be saved in the battery for the family electricity, so that the double complement.

Solar PV complement is a set of power generation application system. The system uses the solar cell array and wind generator (converts alternating current into direct current) to store the electric energy emitted into the battery. When the user needs electricity, the inverter converts the direct current stored in the battery into alternating current and sends it to the user's load through the transmission line. It is the wind turbine and solar cell array two kinds of power generation equipment together to generate electricity.

The wind-PV complementary power generation system is mainly composed of wind turbines, solar photovoltaic cells, controllers, batteries, inverters, AC and DC loads, etc. See the attached drawings for the system structure. The system is a composite renewable energy power generation system integrating wind power, solar power, battery and other energy generation technologies as well as system intelligent control technology.

(1) The part of wind power generation is to convert the wind energy into mechanical energy by the wind turbine, convert the mechanical energy into electric energy by the wind turbine, and then charge the battery through the controller, and supply power to the load through the inverter;

(2) The photovoltaic power generation part uses the photovoltaic effect of solar panels to convert light energy into electric energy, and then charges the battery, and converts direct current into alternating current through the inverter to power the load;

(3) The inverter system is composed of several inverters, which change the DC in the battery into the standard 220v or 240V AC, so as to ensure the normal use of the AC load equipment. At the same time, it also has the function of automatic voltage regulation, which can improve the power supply quality of the wind-solar complementary power generation system;

(4) The control part continuously switches and adjusts the working state of the battery group according to the sunshine intensity, wind strength and load changes: on the one hand, the adjusted electric energy is directly sent to DC or AC load. On the other hand, the excess energy is sent to the battery bank for storage. When the power generation cannot meet the load needs, the controller sends the electric energy of the battery to the load to ensure the continuity and stability of the whole system;

(5) The battery part is composed of multiple batteries, which play the role of energy regulation and load balance in the system. It converts electricity output from wind and photovoltaic systems into chemical energy and stores it in case of power shortages.

According to the variation of wind and solar radiation, the wind-PV complementary power system can operate in the following three modes: the wind turbine alone supplies power to the load; The photovoltaic power generation system supplies power to the load separately; Wind turbines and photovoltaic systems combine to supply power to the load.

PV has the following advantages over wind power or photovoltaic power alone:

● Make use of the complementarity of wind and solar energy, you can get more stable output, the system has higher stability and reliability;

● In the case of ensuring the same power supply, can greatly reduce the capacity of energy storage battery;

● Through reasonable design and matching, it can be powered by the wind-solar complementary power generation system, which can obtain better social and economic benefits.
